[Electronics-Talk] need to know how tv and radio reception would be with metal roof

Tue Nov 9 22:21:35 UTC 2021

When my mom lived in her mobile home, we put up a tall mast and mounted a TV 
antenna at the top with a roter that could be controlled from inside the 
house.  The pole needs to be high enough to clear the roof of the home.
